Finally won my first honest win a little while ago.
By honest I mean I actually helped or it wasn't just a clean up job after two other squads were blasting the hell out of each other. It was just me and a Wraith versus them and it just felt so, so good. I was using the G7 Scout(and the Alternator) for most of the match so when the Wraith iced their Kraber wielding guy she pinged it for me and it was on. Sniped a guy through a window and then my Wraith partner basically ran out into the open and dropped her portal to draw the last one out.
I was having a really shitty run for awhile, people who don't ping are the devil, but here it was pure simpatico. Nothing better than seeing those big Kraber-created numbers pop up for the win.
edit: And for anyone who is seeing this and enjoys the game but laments just how completely terrible they are I really hope you stick it out. I was so terrible initially, heck I am still pretty terrible, but you do get better even if it is slowly. I went from someone who on more than one occasion fired many, many bullets and still lost the match having done zero damage to being...well if not a great a shot, at least someone who can consistently put up numbers no matter how meager.
